A little over a week ago, a Cumbrian woman named Joyce broke her foot. What happened next to Joyce’s foot involves the National Security Agency, decades of deferred maintenance on broken software, a hacking group that communicates exclusively in broken English, and an unsophisticated piece of ransomware, all interacting with the global network that almost everyone depends on now.

The success of the WannaCry ransomware that tore through Eurasia over the weekend required a chain of failures. Stopping any one of these failures could have stopped the crisis, and could still stop some of the crises that might otherwise occur. This makes a difference the in lives of normal people who have nothing to do with any of these global players in the computer security game, and it frustrates them.

Before she left, she was given another appointment for Friday, May 12. It turned out to be the day the NHS fell victim to the largest ransomware attack in history.

“Embarrassing that my home PC [is] vastly better tech than the vastly more important health service,” Leslie, a retired electrician in South Cumbria, tweeted on Sunday.
